| Research Abstract |
In this study, we theoretically analyzed the optimization methods using coupled nonlinear dynamics in which multiple search points driven by nonlinear dynamics implement optimization. Furthermore, we studied an organization of the optimization method using nonlinear dynamics. In consequence, we theoretically explain effectiveness of the introduction of coupled dynamics to the optimization method. Furthermore, we proposed optimization methods using coupled nonlinear dynamics for constrained optimization problems and multi-objective problems. In addition, we proposed an optimization method using coupled gradient dynamics with inertia. These fruits contribute to organize the optimization methods using coupled nonlinear dynamics.
